A 5-map campaign set in various locations throughout Japan. Survivors start in Tokyo's red light district, escaping to Kyoto's Kiyomizu temple, before moving further into the mountains the next morning.
Includes versus mode, which works but wasn't tested much as it was only included as a bonus. Also includes survival mode in 3 of the 5 maps.

awesome design- run down and creepy, especially in later maps
change of scenery shows us as much of the country as possible.
lots of ammo and supplies

Cons:

way to go sometimes not obvious
bots didn't want to get inside map 2 saferoom, or the cable car the first time. once on map 4, they watched a smoker get me and let me die.
scavenge finale.
some areas lagged

Conclusion:

This is a must play for anyone. Though it's long, there are enough supplies laying around to keep you going. I'm not much of a fan of scavenging finales, but this is one of the better ones. Bots in some places are almost too stupid for it to be playable, but they still function well enough that it's a minor annoyance.

-Very detailed
-Liked the intro
-Never seen a map like this Before
-(Spoiler Alert) finding gas and going down for the helicopter
-Traveling you to another city Hard Core
-Outstanding Atmosphere

Cons:

-I saw 6-10 ERRORS which is annoying
-Cars looks unrealistic
-Most of the door cant be opened

Conclusion:

A very Good map all I can say which is I recommend you playing it.
Ignore the Errors (I didn't Ignore it I went crazy so Ignore it)
Good for playing with friends
And the map creator is the best
P.S.
Do I look Beautiful

Very well made
Refreshingly complex
Moderately challenging
At times, i felt like i had to actually fight for survival (Played on Normal)
Very well placed items and weapons
Remarkably realistic
A nice change of pace from normal custom campaigns

Cons:

The only things keeping this from a perfect 10 are two issues with the finale. If you're hanging on an edge, the AI seems to forget your existence and you're left hanging (pun intended). Also, there's a chance that a Charger will come and blast you off the roof of the hotel, resulting in an instant game over.
Not really a con, but there's an overabundance of bilejars in chapter 1.

Conclusion:

While it can run pretty long (my first playthrough was 2 hours 22 minutes), I would call this an essential addition to any custom campaign collection. Very well made, and apart from a few small issues I consider it to be perfect.

• Excellent ambientation - it really looks and feels like a cramped Japanese city when chaos strikes
• Amazing use of special effects (dat plane crash!)
• The tram ride is definitely an original; I've never seen a transportation across a map like that save for the comparatively poorly implemented boat in SaltHell Park

Cons:

• No Magnums anywhere and super-rare melee weapons, forcing players to go with pistols or pistols (-1.0)
• In the first map, there are SEVERAL spots where there are unjustified hitboxes on the street that can get you stuck - horrible when facing a tank (that's a critical flaw: -2.0)
• Washed-out graphics from the second map and onwards; come on, Japan is beautiful, I wanna see some colors! (-0.3)

Conclusion:

Good and worthy of a re-play or several once you get over the problems, but it can get frustrating at times.
A warning to anyone that judges this based on graphical errors: DOWNLOAD THE MISSING CONTENT FIX ADD-ON FIRST. It's not the devs' fault that Valve ripped those elements from the game with an update, and that's happened to several campaigns, so don't make moot points in your reviews.
